چکیده

For spaces of analytic functions defined on an open set in $\mathbb{C}^n$ that satisfy certain nice properties, we show operators preserve shift-cyclic are necessarily weighted composition operators. Examples for which this result holds true consist the Hardy space $H^p(\mathbb{D}^n) \, (0 < p \infty)$, Drury-Arveson $\mathcal{H}^2_n$, and Dirichlet-type $\mathcal{D}_{\alpha} (\alpha \in \mathbb{R})$. We focus when $1 \leq \infty$, converse is also true. The techniques used to prove main enable us a version Gleason-Kahane-\.Zelazko theorem partially multiplicative linear functionals more than one variable.

Composition operators acting on weighted Hilbert spaces of analytic functions

In this paper, we considered composition operators on weighted Hilbert spaces of analytic functions and  observed that a formula for the  essential norm, gives a Hilbert-Schmidt characterization and characterizes the membership in Schatten-class for these operators. Also, closed range composition operators  are investigated.

Irreducible Multiplication Operators on Spaces of Analytic Functions

Mφ : H → H for φ ∈ H∞(Ω). We mention some known results in this area that serve as a motivation for the present paper. First, if H is the classical Hardy space of the unit disk D, and if φ is an inner function on D, then Mφ is a pure isometry and a shift operator on H , and so its reducing subspaces are in a one-to-one correspondence with the closed subspaces of H (φH). Therefore, the reducing ...

Pointwise multiplication operators on weighted Banach spaces of analytic functions

For a wide class of weights we find the approximative point spectrum and the essential spectrum of the pointwise multiplication operator Mφ, Mφ(f)=φf , on the weighted Banach spaces of analytic functions on the disc with the sup-norm. Therefore we characterize when Mφ is Fredholm or is an isomorphism into. We study also cyclic phenomena of the adjoint map M ′ φ.

Semigroups of Weighted Composition Operators in Spaces of Analytic Functions

We study the strong continuity of weighted composition semigroups of the form Ttf = φ′t (f ◦ φt) in several spaces of analytic functions. First we give a general result on separable spaces and use it to prove that these semigroups are always strongly continuous in the Hardy and Bergman spaces. Then we focus on two non-separable family of spaces, the mixed norm and the weighted Banach spaces. We...
